Install bitcoin ubuntu server tutorial

Bitcoin is a crypto-currency. You can also call it a virtual currency as well. It was created by Satoshi Nakamoto. You are your own bank. There are no transaction fees in Bitcoin. So the person you send Bitcoin to will receive the exact amount you send, and if someone sends you Bitcoin, you will also receive whatever amount they send.

Getting Started


The goal of this guide is set up a Bitcoin Node that is useful for tinkering with as a developer. If you complete this guide successfully, you'll have a node that is in sync with the network, contains the full history of the Bitcoin blockchain, and is fully validating all transactions.

This means you can interact with the Bitcoin Network at large without relying on any trusted third party. As a simple example of what can be done with this, we'll run an open source block-explorer, providing you with a trustless interface to view activity on the network. Because this guide is for developers, it assumes you're comfortable doing developery things, such as running Linux, using bash, and executing Python scripts.

Where more in-depth usage of some other tech is an out of scope pre-requisite, I'll provide links to useful guides as appropriate for those portions. If you're looking to run a full node as a standard user, check out the guide on bitcoin.

I run my node with fast residential broadband on a 6 year old desktop PC. It runs like champ! The Bitcoin Core team's focus on making it possible for anyone to run a node truly has paid off. The Bitcoin network follows a protocol for communication and consensus. While several clients for this protocol exist, the "canonical" and most widely used version is referred to as Bitcoin Core.

Each method has its tradeoffs. In this guide, we'll opt for using apt and the PPA, because it's the simplest and easiest way, and makes upgrading to new versions of the software easy as well. One downside is it requires trusting the software that comes from the PPA which could, for example, be compromised by an attacker. Please evaluate these tradeoffs yourself and choose the method thats best for you.

If you're just using your node for development and tinkering and want to proceed with option 3, simply run the following commands and follow the associated prompts:. When these commands are complete successfully, run bitcoind -version. You should see some output showing the version of the bitcoind software you're using. Remember, this is a full node! That means it stores and validates the full history of the blockchain, starting from the very first block mined by Satoshi himself.

That history will need to be downloaded. Unfortunately, this process takes a while and requires about GB of disk space as of today. On my reasonably fast residential internet, I was able to download the full blockchain in about 4 days.

Your mileage may vary based on your connection and geography. This runs the bitcoind process in the background with transaction indexing on. You may also want to start this process automatically on every reboot as well. You can do this by running: crontab -e and adding the following line:. Note that we didn't add the txindex option to the crontab. Later in this guide we'll put this option in a config file instead, which is a better way to set options for your node. Let's navigate there now and poke around:.

You'll notice a number of files and directories have been created. We'll examine just a few of these now. First, run tail -f debug. You'll notice a series of log messages that look something like this:. When the node first begins syncing, these may be flying by pretty fast. Hit Ctrl-C to quit tailing the file and examine the messages. These messages represent blocks being downloaded from the network.

The one shown here represents the latest block mined at the time I'm writing this tutorial, but you'll be well behind this. To monitor the progress of the initial download, you can tail this file and look at the historical date you've caught up to.

Note that, since most blocks early in the network's history were mostly empty, early blocks will download fast. As you get further along, download times will increase. My node spent a majority of the time downloading blocks from onwards. You can also interact with the blockchain using the bitcoin-cli command line interface. For example, you can run bitcoin-cli stop to safely shutdown your node, or run bitcoin-cli -getinfo to get a summary of your node's status:.

One more small piece of fun. You won't normally interact with this data directly, but try running this quick command:. Do you recognize that sentence? If you do, it might send chills down your spine to see it on your machine! If you don't, go Google it and learn why it should. As mentioned, initial block download is going to take at least a few days. During this phase, the daemon may use a lot of resources. Once you're caught up, running the node software has a negligible effect on performance with even a modest machine.

If you've made it this far, bookmark the page and come back in a few days when your node is in sync! Welcome back! It's time to configure your node to act as a JSON-RPC server, so we can run and write code in our favorite language to interact with it. Navigate back to the bitcoin directory and create a flat-text file called bitcoin. Henceforth, this file will be read when bitcoind starts and will be used to configure options for your node.

There are a number of options you can set, and each of these can also be set at command line as well. To get a sense of the options available to you, run:. Open up the bitcoin. This is a good start, but not sufficient to enable RPC interaction with our node. To do so, we also have to create authentication credentials for the user who will log in. It used to possible to specify a username and password in flat text in the config file, but this method is clearly insecure and has been deprecated.

Instead, we have to provide the username along with the hash value of the password-- in conjunction with a salt used during hashing. To generate this, use the following commands to download the canonical Python script provided by the Bitcoin Core team and run it with your own username and password.

Be sure to replace the username and password values with something sane! The script should produce a result like this:. As instructed, add this line to your bitcoin. To test this out, try running the following command note: you may have to install curl first via apt. Be sure to replace myusername with username you actually created.

You'll be prompted for the associated password, and if all worked properly, you should see something like the following:. To learn more about the full set of API calls available, and various libraries that exist that wrap the API, checkout this reference on bitcoin. This is fine if you'll be developing on the same box the node is on, and you can skip this section. If you're developing from a different machine, like a Windows or macOS computer, you'll have to use the rpcallowip option to whitelist IP addresses which are allowed to make calls, and also ensure port is reachable.

Note that a VM, though running on the same hardware, does in fact have a unique IP. Note that you can include this option more than once to whitelist multiple IP addresses. The specifics of finding your development machine's IP and making port available on your node are dependent on your platform and network. These are left as an exercise to the reader. Here's an example of what your final bitcoin.

With your full node up and running, synced to the network, and configured for use as JSON-RPC server, it's time to run your own local blockchain explorer! We'll use the open source btc-rpc-explorer , created by Dan Janosik. This explorer is great because it doesn't use a database-- it just needs access to your node, which it interacts with via the RPC interface we just configured.

If you don't already have these, checkout the instructions for your development platform of choice. Once Node and npm are ready to go, clone the repo from GitHub and build it with the following commands which assume a Unix dev environment :. If you're dev box is not the same as your node, you'll also have to update the host parameter to the IP address of your node.

Note also that your router may assign either you development box or your node a new IP in the future. Look into configuring static local IPs based on MAC addresses in your router's config panel to solve this issue. With the credentials updated, you're ready to run the explorer. Happy hacking!

Installing bitcoind The Bitcoin network follows a protocol for communication and consensus. You can do this by running: crontab -e and adding the following line: reboot bitcoind -daemon Note that we didn't add the txindex option to the crontab. Server Configuration Welcome back! To get a sense of the options available to you, run: bitcoind --help Open up the bitcoin. The script should produce a result like this: String to be appended to bitcoin.
